A must have for a smooth browser experience in firefox.

For other mac users: You can find the default shortcuts in the firefox add-ons manager after installation and you can even change these shortcuts there.

My most heavily used shortcuts, can't live without.

Must have since the time Firefox hid the option 'Close all tabs besides this one' below a submenu.
Nice that you can set the shortcut keys yourself. I personally use Ctrl+F12 to close all tabs right of the current one and Ctrl+F11 to close all tabs but the current one.

Quite easy extension, source code seems legit. Many thanks

Wish we could modify shortcuts or see existing ones from this extension of right-click menu.

I reviewed the extension source code and it's a simple extension that works and doesn't do anything it shouldn't.

It's a must-have. These shortcuts really lack in Firefox. Although, the capacity to edit shortcuts is simply lacking in Firefox.

大量のタブを閉じる際に右クリックメニュー → 右から閉じる、ができていたあのに新しいFirefoxになってから、間に「複数のタブを閉じる」が入っていちいち邪魔。タブなんて閉じたり開いたりを繰り返すんだからなんたってそんな仕様変更したのか。このアドオンは右クリックすらなく左手一本ショートカット一発で閉じてくれる。こういうの本当に嬉しい

This add-on is just what is needed, especially since Firefox developers have decided to bury the "close tabs to the right" into a nested context menu item (at least on Nightly) More clicks to perform a simple task.

Thanks to the developer of this addon ! I can now close other tabs with a simple / customizable keystroke. VERY useful!

I was already using a similar add-on needing an icon to be clicked but I'm an old shortcut-key fan! This is perfect for my needs - many thanks indeed. May I suggest, to save having to Ctrl-T/Alt-W to carry on from a fresh, single tab, you allocate a single hotkey combo to do both in one stroke?
